FOUNTAlN-PEN.

SPECIFICATION forming part of Letters Patent No. 605,035, dated May 31,1898.

l Applioation filedwl'une so, 1897. Serial No. 642,991. (No model.)

To all whom it may concern-: I

Be it known that I, JOHN W'EEKS, of Brooklyn, in the county of Kings andState of New York, have invented a new and Improved Fountain-Pen, ofwhich the following is a full, clear, and exact description.

The object of my invention is to construct a fountain-pen in suchmanner. thatbut few parts need be employed, all of them being readilyassembled or disconnected,thereby providing for a thorough cleansing ofthe pen. Another object of the invention is to so construct the pen thatby the manipulation of an exterior portion the flow of ink will be underperfect control at all times in opening and closing.

A further object of the invention is to provide a pen wherein thesupply. of. ink to the nib may be cut off to such an extent that the penmay be carried point up or point down without danger of leakage, andwhereby, further, the ink cannot corrode, since when it is held in thebarrel it will be air-bound.

The invention consists'inthe novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Referenceis to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both the figures.

Figure l is a longitudinal section through the barrel of a pen, theother parts being shown in elevation; and Fig. 2 is a longitudinalsection through the entire pen.

The barrel A may beof any size and is closed at the top with theexception of an opening 10, through which a stem 11 is passed, the saidstem carrying at its lower 'end a plunger 12. At the upper or outer endof the stem 11 a knob 13 or its equivalent is secured, by

means of which the stem may be turned, and the stem is prevented fromhaving end movement in the barrel, although it maybe freely turnedtherein by attaching a collar 14. to the stem immediately below theunder face of the upper-closed portion of the barrel, the lower portionof said barrel being open. The plunger is provided with a suitablepacking which engages with the inside wall of the barrel, and

' the plunger is held to travel up and down the lower portion of thestem 11, which is provided with an exterior thread llflas shown in Fig.2. At the lower portion of the plunger a tubularextension 15 is formed,of less diameter than the plunger, and the upper end of the valve-rod 16is secured in the tubular extension in any suitable or approved manner.

A pen-sleeve 17, in which the nib or pen is placed, together with thefeeder, is attached in any suitable or approved manner to the nose 18,which nose is screwed into the lower or open end of the barrel. Theupper or inner end of the nose is closed except that an opening 19 isformed for the passage of the valverod 16 to the'chamber within thenose, and

immediately below the top or inner end of the nose in which the opening19 is made a valve-seat 20 is formed, adapted to accommo date avalve 21,secured to the aforesaid valverod.

In operation by raising the piston in the body barrel or reservoir ofthe pen through the medium of the screw attached to the knob at thetopof the reservoir a vacuum is produced in the body, barrel, orreservoir which will cause the ink in the feeder and pen to.

return to the reservoir or barrel, where it will be held by the seatingof the valve. WVhen the pen is to be used after the ink has been lockedin the reservoir or barrel, the piston is depressed or made to traveldownward in the barrel,'which will unseat the valve and permitthe ink toflow to the pen in required quantities. The valve when seatedeffectually prevents the ink from flowing to the point of the pen, andtherefore the pen may be carried in any positionnamely, point up orpoint downwith safety.

The filling of the pen with ink is accomplished by removing the sleeve17 from the nose 18, unscrewing the nose, and feeding the valve-roddownward until the nose can be separated from the barrel. The ink maythen be introduced into the barrel.

'It is evident that a pen constructed as above set forth is exceedinglysimple,'comprising but few parts, and that thesupply of ink to the nibwill be completely under the control of the operator.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a ton ntain-pen a barrel having a val veseat, aplunger held to travel in the barrel, a valve controlled by the plunger,adapted for engagement with the said seat, and means for opera-ting theplunger, substantially as described.

2. In a fountain-pen, a plunger, and a valve connected therewith,located within the barrel of the pen, the plunger being arranged to drawthe ink from the nib or to force the ink in direction thereof, the valvecontrolling the supply of ink to the nib, as specified.

3. In a fountain-pen, the combination with a barrel, of a plungermovablelongitudinally within the barrel of the pen, and a valveconnected with the said plunger and located within the barrel of thepen, the said plunger when moved in one direction drawing the ink fromthe nib and when moved in the opposite direction forcing the ink towardthe nib, the said valve controlling the supply of ink to the nib,substantially as specified.

it. In a fountain-pen, the combination with a barrel having its lowerend provided with a chamber communicating by a contracted opening withthe interior of the barrel, and a valve controlling the passage ofmaterial from the body of the barrel to the said chamber, the said valvehaving a rod extending upward into the barrel, of a plunger connectedwith the upper end of said valve-rod, and means for imparting movementto said plunger longitudinally of the barrel, substantially as setforth.

In a fountaiirpen, the combination with a barrel having its lower endprovided with a chamber communicating with the interior of the barrel,and a valve controlling the pasage of material from the body of thebarrel to the said chamber, of a stem arranged to turn in the upperportion of the barrel and held against end movement, the said stem beingcapable of being operated from the outside of the barrel and having itsinner or lower end threaded, and a plunger arranged to travel on thethreaded portion of said stem when the stem is turned, said plungerbeing connected with the said valve, substantially as described.

6. In a fountain-pen, the combination with a barrel, and a stemextending through an opening in the top of the barrel and fitted to turntherein, the outer end of the stem being provided with a knob by whichthe stem may be turned, the said stem being provided inside the barrelwith a collar to prevent end movement and the lower portion of the stemwithin the barrel being provided with an exterior thread, of a plungerheld to travel upon the lower threaded portion of the stem, the saidplunger having a tubular extension at its lower portion of less diameterthan the plunger, a nosearranged to carry a pen-sleeve at its lower endand screwing into the lower end of the barrel, the said nose beingformed with a chamber and having a contracted opening in its topconnecting said chamber with the interior of the barrel, and a valvearranged to control the passage of material from the body of the barrelto the said chamber, the said valve being provided with a rod extendingupward in the barrel and connected at its upper end to the tubularextension of the plunger, substantially as shown and described.
